Application filed October 19, 1912. Serial No. 726,599.

To all whom it may concern:

Be it known that we, Go'r'rFRInD BliHR and HAns DOBESOI-I, both citizensof Germany, residing at Schramberg and Stuttgart, Germany, respectivelyhave invented certain new and useful Improvements in Containers HavingAppliances for Discharging the Contents Thereof, of which the followingis a specification.

This invention relates to containers such as cruets, more particularlymustard containers of the type in which the contents are forced out bymeans of a piston or plunger. In the mustard containers of this typeheretofore designed, in which the plunger, after being depressed todischarge the mustard, is raised again by a spring and ascent sucks themustard back from the discharge orifice, the plunger always returns tothe same position. If this normal position of the plunger is above thelevel of the mustard the plunger is liable to discharge too much mustardwhile the container is well filled, and too little when the container isless full. If the'normal position of the plunger is in the mustard, andthe plunger is arranged so that the length of its stroke does not vary,air penetrates to the space above the mustard, and causes the same todeteriorate.

The object of the present invention is to remove these disadvantages andto provide a mustard container wherein the extruding plunger always liesabove the mustard but is, after each extrusion, only withdrawn to anextent suflicient to suck the mustard away from the discharge orifice.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a vertical section showing one embodiment thereof. Fig. 2 isa vertical section showing another embodiment, and Fig. 3 shows a detailthereof in another position. Figs. 4 and 5 are views corresponding toFigs. 2 and 3 showing a modification.

Referring in the first place to Fig. 1, a is the container, which has adischarge-orifice b, and is closed at the top by a screw cover a; (Z isthe piston or plunger attached to the rod 6. The latter is screwed atits upper end to a knob 9 against which bears a spring h coiled upon therod 6. The lower end of the coiled spring abuts against a shoulderinside a sleeve 2', in which the rod 6 is slidable and rotatable. Thesleeve 2' is slidable in a boss 70 on the cover 0, but is embraced andgripped by a spring ring on which is arranged in a groove inside thesaid boss 72. The sleeve 2' is of such length that a short depression ofthe knob 9 causes the latter to abut against the upper edge of thesleeve. When the knob g and the plunger are depressed for the purpose ofdischarging mustard, the spring I). is compressed. If the pressuretransmitted by the spring h to the sleeve 73 exceeds the force withwhich the ring m grips the sleeve or if the knob. g is thrust downsufliciently to abut against the upper end of the sleeve and depress thesame, the sleeve takes part in the latter portion of thedownward movement of the plunger. When the knob g is then released, the sleeve 2'remains stationary, whereas the plunger is raised by the spring it untilit abuts against the lower edge of the sleeve 2'. By this slight upwardmovement of the plunger d, the mustard is sucked away from the orificeb. It will be seen that each return stroke of the plunger afterdischarging mustard, is somewhat shorter than the previous downwardstroke. Accordingly, the plunger follows the descending level of themustard in the container. In stead of being at the bottom of thecontainer, the discharge orifice may be at the side.

In the construction shown in Figs. 2 and 3, the plunger (Z in thecontainer 64 has a rod 0 extending upward through a hole in the boss 79on the cover 0 the arrangement of these parts being exactly similar tothat of the corresponding parts shown in Fig, l. The rod 6 however, hasa screw thread 1 of very coarse pitch at its upper part, and has a crank2 fixed to its upper end, this crank being connected by a coiled springhi to the sleeve '5 The latter is in part internally screwed, to engagewith the screw 1, and is also externally screwed, to engage with thetapped boss 7: The plunger 01 is normally held against the lower end ofthe sleeve 2' by the action of the spring [2, which tends to screw therod 6 upward in the sleeve. When the crank 2 is turned against theaction of the spring h the plunger rod 0 descends inside the sleeve iuntil the spring 72. has been fully compressed, as shown in Fig. 3,whereupon further rotation of the crank rotates the sleeve 2' and causesit to screw downward through the cover When the crank 2 is released,after the dis charge of the required amount of mustard, the sleeve 2'remains stationary whereas the rod 0 with the plunger d is screwedupward by the action of the spring k until the plunger abuts against thelower edge of the sleeve.

The device shown in Figs. 4, and 5 is similar to that shown in Figs. 2and 3, except that a coiled plate spring it is substituted for the wirespring N.

The container may be made of china, glass, "celluloid or the like, andthe plunger of cork or other suitable material. The springs and the ringm are preferably made of steel.

V \Vhat we claim as our invention and desire to secure by Letters Patentof the United States is 1. The combination, with a container having adischarge orifice, of a plunger movable in said container toward andfrom said orifrom said orifice, an abutment movably engaged with saidcontainer in the path of said plunger from 'said orifice, and meanswhereby movement of said plunger toward said orifice imparts movement tosaid abutment after said plunger has traversed part of its path.

2. The combination, with a container having a discharge orifice, of aplunger movable in said container toward and from said orifice, aplunger rod extending out of said container, a movable sleeve embracingpart of said rod and frictionally engaged with said container, and aspring engaged with said sleeve and said rod, allowing limited movementof the latter in said sleeve and tending to move said plunger from saidorifice.

In witness whereof we have hereunto set our hands in the presence of twowitnesses.
